A locking device for providing access to a structure includes a locking mechanism configured to selectively switch between a locked state and an unlocked state. A wireless interface is operatively connected to the locking mechanism to control change between the locked and unlocked states. The wireless interface is configured to periodically beacon a data packet providing information to listening devices in a local area without requiring a bi-directional connection and to support bi-directional connections as needed to transfer data to the locking device.
